nologin displays a message that an account is not available and exits
non-zero. It is intended as a replacement shell field to deny login
access to an account.
If the file /etc/nologin.txt exists, nologin displays its contents to
the user instead of the default message.
The exit code returned by nologin is always 1.
nologin is a per-account way to disable login (usually used for
system accounts like http or ftp). nologin(8) uses /etc/nologin.txt
as an optional source for a non-default message, the login access is
always refused independently of the file.
pam_nologin(8) PAM module usually prevents all non-root users from
logging into the system. pam_nologin(8) functionality is controlled
by /var/run/nologin or the /etc/nologin file.
